T0 all whom t may concern:

Be it known that I, PLIN C. SOUTHWICK, a citizen of the UnitedStates-of America, and a resident of Sandwich, countyof De Kalb, and State of Illinois, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification, and which are fully illustrated in the accompanying drawings, forming a part thereof.

In the drawings7 Figure 1 is a perspective View of the press. Fig. 2 is a plan View of the press. Fig. 3 is a detail sectiontaken on the line 3 3 of Fig. 2. Fig. e is a detail section taken on the line et 4 ofFig. 2. Fig. 5 is a detail plan on the line 5 5 of Fig. 6. Fig. 6 is avertical longitudinal section taken on the line 6 G of Fig. 2. y Fig. 7 is a detail plan view of the body of the machine; Fig. 8 is a detail plan in section of the swinging door or bulkhead of the balingchamber, showing grooves for the wires; and Figs. i), 10, 11, 12, 13, and 14 are details of the power device, Fig. 12 being a sectional view on the line 12 12 of Fig. 11.

This invention relates to portabie balingpresses of that type in which pressure is applied to a reciprocating plunger by means of a toggle-joint mechanism; and the invention relates to improvements in various parts of the press and in the power mechanism coperating therewith.

The objects of the invention are to .provide a press of large capacity and capable of substantially-continuous operation; to provide for the baling of the material, suchas hay, in such form that the wires may be applied from side t0 side instead of from end to end;

to provide means for the end discharge from abulkhead-press; to provideimproved means for controlling the door for closing the feedaperture of the compressing-chamber; to provide an improved form of toggle mechanism;

` to provide improved retractin g means, and to improve the power mechanism used; in conjunction with presses of this character. These objects are attained by theconstruction hereinafter fully described and which is i1lus trated in the drawings.

The body or trunk of the machine is a strong oblong rectangular chest A of greater width than height, having' a suitable framing and being open at one end, the other end being closed by an openable bulkhead. The inte rior of, this body is divided into a compres# sion-chamber a anda baling-chamber a', the 55 two being separated merelyby the spring-'res taining pawls a4 aiglpast whichthe'material is forced in the actof compression from 'the chamber a into `the chamber a'. A commodious feed-aperture a2is provided in the top 6o of the body portion of the machine opening to the chamber a.

The discharge end, which I characterize as the front end of the machine, is closed by means of a bulkhead-.doorB, hinged across the top to the framing of the body,- as shown at b, and being lagged out 4at its lower end by a block b. The door B is locked in its closed position by means of a lever-arm C, pivoted, by means of the link c and the eyebolt c', to 7o theend of' the crossrail of the frame of the body portion, so that it may be swung upwardly to bear against the lagging-block Il and have its upper end caught by `a loop c2,

vswinging from the end cross-beam at the top 7 5 of the body A, this loop being provided with an upwardly #extending and y backwardlyturned handle-bar cwit'hin 'easyl reach'of an operator standing on the -top of the machine.

As thecompletedbale is intended to be dis- 8o charged by the pressure against it'of the next succeeding charge of thematerial tobe` com- Amessed; I provide means i for imiding! this new charge after the bale has 'fallen from Vthe press anduntil the doorB has closed 4 and 85 been secured. Such means consist of the ngers c4, projecting into the chamber a' from above and below and being carried bythe spring-plates 0505, secured to thetop and bottom of the trunk or body of the machine 9o and being reinforced, if necessary," by spiral springs c6 c6, reacting against suitable brackets attached to the framing of the machine. The fingers c4 have their front faces slightly beveled, so that the final compression of'the 95 material will cause their retraction; the spring, however, controlling them being. of sufficient tension to hold the material in place untillthe bulkhead-door has been secured.

The plunger-head D reciprocates longituroo dinally in the chamber a and "carries a backwardly-projecting framework d in box form, which serves as a suitable guide for the plunger and also as a table for closing the aperture a2 when the plunger is at the end of its instroke, Iso that material for the next charge may be deposited upon it without waiting for the retraction of the plunger.

The long arm of the toggle is attached to the rearward face of the plunger along its hori-E zontal median line Aand comprises the two bars, preferably I-beains E E', arranged in V form, their rearward ends converging, so that their forward ends engage the plungerhead D near its side edges. The shorter arm of the toggle comprises the Atwo bars F Ff, arranged in V form, the apex of the V being pivotally united with thelonger arm oftheV toggle some distance from its rearward end. The two bars F F of the shorter arm ofthe toggle are rigidly'fixed to a shaft G, journaled' in suitable boXesat the rearward ends of the sideV sills of the body portion of the machine. l Crank-arms gg are fixed upon the-extreme ends of vthe shaft vGr and are connected by means-of chains gtand coil-springs g2'with the frame ofthe'bodyportion of the machine, the'angular relation ofk thecrank-arms'gfgl and the short arm of the tog-gleand the length of the connecting chains andsprings `being suchthat these connecting media are'drawn --taut'asthe toggle approaches thelimitvo'f its backward movemenso that the springsg2 cushion the outstroke.

Power is'applied to the toggle by Ineansof alllink zH, attached, as shown at @,totheapex of theV-shaped long armthat is fto say,"the point o'f--attachment is back of the j oint-of the toggle. Achain h connectstheilin'kHwith ltheipowermechanismJ hereinafter described, and isturned overa sheave hlrunning upon the shaft G,so"fthat the initial strain; i'n-straighteningfthe'toggle is transverse to theshort arm ofthe latter, the ychain thenpassing'around a sheave h', suitably jour-naled below the body Ain suchposition that the directionof vthe-final Lstrain is'snbstantially perpendieiilar tof-the-straightened toggle.` 1

The feed-door K is pivotedacrossltherearward'side of theaperture a2 and oscillates-'in and out of the feed-hopper. This door isprolvided at its louterxedge with suitable stophooks Zc,'-adapted to yengage the cross-beam d5 ofthe body portion Arat thefor-ward'edge of .the aperture d2 and to allow theinner face ofthe door'K toV comeiiush with they topeo'frthe chamber a. Spring-bolts k 7c' are carried'by the door K and adapted toengagesuitable sockets inthecrossbeam a5, -soas tofsecurel-y lockthedoorinitsclosedposition. Thebolts cfarefconnectedwith the crank-arms'kz, carried bya v'rock-shaft ksuitably rjournaled across the outer face ofthe doorlK, andxthis shaft/is provided with a third crank-m1112794, to :which and to the face of the doora spiral spring cis attached, s0 as ito nor-mallyihold the bolts vin their extended'position. iT-heiretr'action of thebolts isaccomplishedfby'means of vachain .k6 alsol attached 'ztozthefcrank-arm tandv afterV being turned aboutxasheave 707, journaledin a suitable bracket securedto a bracket also carried by the frame S.

frame los, vbuilt up from the body of the Inachine, is secured, as shown at'cf, to the outer end of a lever-arm Z910, pivoted in a suitable The retraction of the bolts k is automatically accomplished by means of a loop e', projecting =upwardlyfro1nthe long arm of the toggle and adapted to engage and depress the short end of fthe lever 7610, the first movement of this lever accomplishing the retraction of the bolts and throwing the crank-arm 7a4 against a block 1011, standing up frointhe'face of the door immediately back of the rock-shaft k3, so that ythe furthermovement of the lever Z010 lifts the door K. The front wall of the feed-hopper is provided with suitable camways a3, as shown, for'the engagement-of the ends of the bolts 7c', forcing theminwardlyas 'the door :VK descends in order that they may Kengage the sockets in the cross'beamA d5. `Thefretraction o'f'the ,plun ger Viis accomplished 'fby means of thechain'M, leadingzfrom'the power mechanismfa'nd bearing 'uponItheA outer face of y a camseg'ment mandfbein-g attached ,to fthe'latter -at its.fshortestradius. The cam-isegmentm is mounted'uponztheshaft'G, buteccentrically: thereto, soy asto move ,-withrfthe short Varm oftheftoggle. y

The machine iis adapte-d to be driven by horse-power, andthe power comprises arsnitable frame TO, which,-as r-shown, is approximately V-shaped and Vupon-whichv is pivoted a draftfpole P. fl-o'thepivotfpin ofathedraftpole P-thereislflxed an eccentric-cam-block p, kwith which -the chainJz;isrperiodicallyenga'ged` andupontherperiphe-ral face of which it is laid'as the'camfisfturned. 'Theengage- 'ment of y'the chainfh with "the `cam p i-s by means of a hook h3 at the en'd of the chain and a reciprocating'pawlp',adapted to be projectedinto the Ypath of `the hook. The

' eamblockip is provided with-aperipheral i'l'- groove, :into which :the nose of the y-hookh3 enters and fwithin which 'it isretained 'by meansof-asuitable cross-pimasshown. The

V"Fog-nard againstfthis, I provide ardog T, which is arranged to be thrown into the path of :the hooklasthe pawlp is retracted "and to be withdrawn therefrom-as the .pafwl saganJa'adVanced.

crank and is pivoted att within a suitable recess in the frame of the cam p, so that its nose will enter the groove within which the hook h3 runs. The heel end t of the dog T is engaged by the pawl p', and to accomplish this conveniently a plate p4 is secured to the pawl and has a lateral recess p5, into which the end t' of the dog enters. By reason of this engagement of the dog with the pawl the reciprocation of the latter causes the oscillation of the former, the nose of the dog being advanced by the recession ot the pawl and withdrawn by its advance. The location ot' the recess p5 with reference to the forward end of the pawl p is such that when the pawl is projected into the path of the hook h3 the dog is withdrawn therefrom, and when the pawl is withdrawn from this path the dog is thrown across it. The dog is located at the forward side of the pawl p', so that it stops the hook as it flies back and holds it until the advance of the pawl retracts the dog and allows the hook to move along the groove and engage the pawl.

The retracting-chain M, after being turned over a suitable sh'eave m', carried by the framing of the body A, leads to and is laid over the peripheral face of an eccentric cam R, pivoted upon theframe ot' the power, the attachment of the chain to the cam being at the shortest radius of the latter. The cam R is provided with a segmental rack r, which intermeshes with a segmental rack S, fixed upon the pole P, and the parts are so disposed that the racks S and r come into engagement immediately after the plunger D has reached the limit of its instroke. As the pole P advances the cam R is moved upon its pivot, so as to draw back the chain M, thereby retracting the plunger. In order to insure a proper engagement of the rack S with the rack fr, the first tooth r' of the latter projects radially to a considerable distance beyond its mates.

The initial movement in retracting the plunger involves the Vertical movement of both members of the toggle, and these members being of very considerable weight more power is required at the commencement of the stroke than at any other portion of it. This is provided for in the eccentric form of cams m R, the initial action of each being by that portion which is at its greatest radius, thereby utilizing the maximum leverage of each cam.

The operation of the press is as follows:

The chamber a having been iilled with the material to be baled the door K is thrown down, pressure being applied, it' necessary, to completely close it. `Power is now applied to advance the plunger, and the charge is compressed into the chamber a', the door K being automatically `opened vby the engagement of the loop e with the lever kw before the instroke of the plunger is entirely completed, and the feed-hopper is at once lled, the material being crowded down into the chamber a as soon as the plunger recedes, and' if the` chamber ot has not been entirely filled the power may be stopped temporarily. From one to four charges will make a complete bale, depending upon the character of the material and the density to which it is desired to compress the bale. The bale having been completed the plunger is stopped at the end of the last instroke, and wires are inserted from above, being passed downwardly in the groove b2 b2 in the bulkhead-door B and d in the face of the plunger D, the two ends of each wire being secured together at the bottom of the bale, the floor and roof of the chamber a being slotted for their accommodation, as shown at oc y. The loop c2 is now raised, releasing the arm C and allowing it to fall. The power is again applied to the machine, and upon the next advance of the plunger D, a new charge in the meantime having been deposited within the chamber a.,

the completed bale is ejected, the door B being thrown upwardly by the power applied through `the plunger. the trunk A is made flaring at the top and bottom, as plainly shown in Fig. 5, in order that the bale may freely drop therefrom. As the bale falls from the machine the charge which has been compressed behind it isheld by the fingers c, and the operator throws upwardly the arm C, the door having fallen as the bale dropped, and makes it fast by means of the loop c2. The bifurcated or V form of the two arms of the toggle rmly brace the parts and strengthen the joint, and the application of this form to the long arm of the toggle makes it possible to use a very wide plunger-head, the danger of the cramping of the plunger by reason of the differing density in the charge being thereby removed. The cushioning-springs g2 prevent injury to the mechanism by reason of the too-rapid descent of the heavy members of the toggleas the limit of the back stroke is reached. By prolonging the long arm of the toggle beyond the joint and applying the power to its rearward end an increase of leverage is secured. The top d of the rearward extension of the plunger is slotted from its rearward end, as shown at d2 d2, forA the accommodation of the two members EE of the long arm of the toggle, and the central tongue d3 between the slots d2 d2 is supported by a suitable brace.
